Chaotic overcrowding has now struck Brussels Zaventem Airport, following the reopening of its departure hall, which was rocked by suicide blasts in March. Stringent security made thousands of passengers wait hours in long queues.

The airport’s departures hall was opened on Monday. “Today we're welcoming the first passengers back into the main #brusselsairport departures hall. An important and hopeful moment. #BrusselsTribute,” the airport wrote on Instagram.

However, passengers had a sticky time passing all the registration procedures. Due to security screening, people had to stand in line for hours, many of them outside the building, some missing flights as a result, the Belga news agency reported.

“3 hours margin to take off from #brusselsairport. Alternatives become attractive,” @FLouagie user wrote on Twitter, while @basverveen said: “What amateurism at the airport #Brussels #mess # Brussels Airport.”
